Dear Bob, Rich, Felloe aviators,

The question on page 4.13 re a flight from Kalkgurung to Tenant Creek Via Hooker Creek applies:

I notice that the LSALT applies, and am presuming that at the time of my books publication the Kalkurung IAL were not in force? (my book is July 2012, bought in 2013), but even so, on the ERC LOW 6, I cant find an answer that relates to the answer of 2600 ft Cloud Base. The Grid LSALT is 2900 feet, and there is no stipulated LSALT on the W605 between Hooker Creek and Kalgurung?

Am I just missing something obvious here, or maybe the ERC have also had an amendment since print.

Much Thanks,

Andy

My apologies chaps,

After having a coffee break, that I should probably have had a hour earlier, I reviewed the question - and with a less weary pair of eyes noticed my mistake.

The W605 is active between Hooker Creek and Victoria River Downs and HAS got a LSALT of 2600. The fact that the LSALT is stated only after passing Kalkgurung has no bearing, it is still relevant for that whole leg, thus the correct answer IS indeed 2600 feet as the answer states.....ah the miracle of coffee and a 10 min break!

The RNAV GNSS approach at Kalkurung did not exist when that question was written and I have since amended the wording to say that you are flying OZY. That means that you cannot use the RNAV GNSS approach because, if your GPS is TSO 129 you need another ground-based aid.

The LSALT was chosen on the assumption that Kalkurung is on W605 so the LSALT of 2600 feet could be used.

Thanks for your feed-back.

Bob

Hi Bob,

This question may need to be updated as OZY has 2 x TSO146a GNSS units now. So You can use the RNAV 03 minima (563-3.2)?

I have updated that. Yet another change. Thanks for your feed-back.
